PATENT OFFICE A CORPORATION OF NEW YORK SEALED PACKAGE y Application filed. May 16, 1927. Serial No. 191,613.

vThe present invention relates generally to the art of sealing and more particularly to a sealed package.

It is customary in sealing certain products ib' such as ketchup, chili-sauce, and the like, to

use two types of closures on each container. One of these is for the purpose of forming a hermetic seal and the other for providing a cover for the container after the hermetic seal Vis removed and to improve the looks ofthe package. This auxiliary cap may be telescoped over and secured to the neck of the container below the upper closure in any suitable manner. Ordinary corks have been used to form the hermetic seal but these are difficult to remove and are sometimes forced into the container, which causes considerable trouble. Olosure caps commonly known as the Grown cork caps have also been used. These require a specialcontainer nish and in addition there is likelihood of chipping the container in removing the cap, thereby getting broken glass into vthe contents. Further,'the seal itself is objectionable due vto the fact that it has an edge seal secured in position by metal-to-glass contact with the lower part of the skirt of theV cap. These and the other seals which have been attempted are not satisfactory.

The present invention overcomes these difiiculties by providing a hermetic side seal on a bottle or the like having` the usual commercial finish. The closure is locked to the container through the intermediation of a ring gasket which holds the metal out of contact with the glass and facilitates removal of the closure. The closure itself is inexpensive and is deformed to reduce its external dimension to a minimum so that a second cover may be attached to the container without material difference in the size thereof.

An object of the present invention is to provide an effective, inexpensive side seal on the side wall of a container. l

`Another object of the invention is to effect a hermetic side seal 'with a minimum external dimension to facilitateV the application of a second closure to the container.V

Another object of the invention is to form an effective side seal on a narrow sealing zone at the mouth of a bottle or the like. f

Afurther object of the invention is toform a side seal on the narrow sealing Zone of a bottle Vby locking the lcap thereon rthrough the intermediation of a gasket. 'f

Other and further objects of the invention will be obvious upon an understanding of the illustrative embodiment about to be de'- scribed; and various advantages not referred to herein will'occur to one .skilled in.y the art upon` employment ofthe invention in practice l ,Y

A preferred embodiment has been chosen for purposes of'illustration and description l` and is shown in the. accompanying drawings, wherein Fig. 1 is an elevational view of a container and closure prior to the sealing operation, with the closure thereon shown in section;

Fig. 2 is a sectionalview, the container being shown in elevation, illustrating one form of sealing operation;

Fig. 3 is a sectional view of an upper closure hermetically sealed to Lthe container and another closure telescoped thereabout and attached to the neck of the container; i'

Fig. 4 is a view similar to Fig. 3 with the outer closure shown threaded to the neck of the container;

Fig. 5 is an enlarged view of a portion o f. the cap showing the change in contour during the sea-ling operation. Described generally the present invention attains the vobjects enumerated herein by -1r 'providinga closure cap having a depending skirt with 'a bead formed therein adapted to support a gasket. The caps may be applied to the containers by automatic machines and likewise sealed by automatic machines. The' bead in the cap has its outer side wall pressed upwardly and inwardly to form a narrow, deepl groove between its upper edge andthe skirt of the cap. This permits the diameter of the cap to be materially reduced and the' gasket to be effectively restricted about the side wall of the container without deforming Y .the outer side wall of the bead. The lower edge of the gasket isV supported so that it is effectively locked against the shoulder below the sealing zone of a container having the usual commercial iinish. A second closure, which may be an ordinary deep drawn screw cap or a deep drawn snap cap, can be telescoped about the upper hermetically sealed cap and attached to the neck of the container.

Referring more particularly to the drawings, there is shown a container 1, here illustrated as a bottle having a narrow annular sealing zone 2 adjacent the mouth thereof. Beneath the sealing zone there is an annular groove l which forms with the sealing zone a shoulder 8. A substantially cylindrical zone 5 may extend from thewgroove 4c to the body of the container where a shoulder 6 may be formed to engage the lower edge'of the skirt of the cap. The zone 5 is slightly larger than the sealing Zone 2 to co-operate with a cap having a skirt sufciently large to be telescoped over the cap on the smaller sealing zone.

A closure cap 7 is provided forvforming a hermetic seal on the sealing `zone 2. This cap preferably comprises acover portion' extending-over the mouth of the receptacle, a downwardly depending` skirt 9 ilared to permit stacking and having an annular bead l0 for supporting a gasket ll. The cap and gasket are placedupon. the containers in assembled state and the. gasket is supported adjacent the sealingzone 2. Y i

Any suitable mechanism may be utilized for effecting the necessary seal. A preferred Vform is illustrated in the drawingswherein a die 14 extends over the cover portion of the cap to hold it firmly in position. The eX- ternal dimensions of the die are slightly less than the external dimensions of the cap, and the outer edge ofthe die is beveled as shown at 23 to permit the formation of a groove in the upper wall of the bead. A roller or spinning die 15 actuated by any suitable means, `(not shown) engages the outer periphery of Vthe bead to spin it inwardly andkto effect the seal. The relative shapes of the roller and die are such that the outer side wall of the bead is spun upwardlyv and inwardly as shown in Fig. 2, when the roller l5 is moved from the dotted line to the full line position. An inturned flange '16 supports the lower portion of the gasket and locks it against the shoulder formed at the lower edge of the sealing Zone.l The spinning upwardly of the outer side wall of the bead forms a narrow annular groove 17 in the upper side wall which greatly facilitates the reduction of the diameter of the cap and at the same time the lower surface of the groove rests upon the rounded edge of the bottle and prevents the gasket from being pressed therebetween. The inturned flange is suciently long to support the gasketffirmly against the shoulder and at Vthe same time permits Vthe engagement of a cap opener for the removal of -thecap. l The gasket is,.therefore, prevented receptacle.

from riding over the upper edge lof the receptacle and is held against the shoulder 3 to lock the cap in position without necessitat ing a metal-to-glass contact.

The outer diameter of the cap permits the application of a second cap 18 as shown in Fig. 3. This cap may engage the lower Zone 5 in any suitable manner as by the projections 19 in the skirt of the cap in'Fig.A 3 or by the threads 20 and 2l on thevcontainer and cap respectively in Fig. 4.- ln either case the second cap may be applied or removed' re peatedly if desired. l

The upper cap 7 when applied tothe con `tainerforms aneiiective hermetic seal which preserves the A contents of thev container so that it may be kept for a long period of time. lVhen sold to the consumer the cap l8`is removed and a suitableopener appliedto the cap 7 for removing it. Thereafter the cap18 is used `as a cover and for partially sealing vsealing operation suihciently to permit the application yof a second cap havinga minimum diference in size. The seal-is formed on the outer side wall of the receptacle and does not, therefore,contaminate the edge of the by irregularities on the upper edge `of the container. Thercaps may bereadily applied and sealed byv automatic machinery and the packages are fully capable of withstanding ,the rough handling to which they may be subjected in transportation.

lhilev the presentinvention has been Adescribed with particularreference' to the Vformation of a seal a't the upper edge of a lbottle it is tobeY understood that vmany of the features are applicablento sealing .generally. lt is desired therefore,,thattheabove descriptionbe takenfas illustrative and not in a limiting sens/e as various otherchanges may bev madefwithout' departing'ifroin the spiritof the invention.' j p Having thus described'my invention, I claim:"'V l.
